KNOW AQLL MEN BY THESE PRESENTS: 'I

That I, EDWARD Wsronr, ofthe city and county ofWorcester, and Commonwealth oiMsuachuletts, have invented certain new und useful improvements in Looms; and I -do hereby dcclsrethst the following ich full, clear, and exact description of the same, reference being had to the accompanying drawings, forming s part of this specification, in which- Figure represents so much of n. loom as is necessary to illustrate my invention.

Figure 2 represents a longitudinal central section o f apart ci" the device shown iniig'. 1, and

Figure 3 represents e crossfsectionpfo part of the device shown in g. 1.

My present improvements relate to the devices used to propel or throw the shuttle in powerlooms.

In the drawings the part marked A represents the picker-stui'to the top of which is uttsched the picker B, whichis composed of s metal shell crease, 0, of peculiar construction, inn'hich isplcccd some iibrcus metcrial D, to receive-tit int of: thel huttie. The `parl; D muy be mcdeofpiecQs of leather, thick paper, or any othes` suitable me `f The,metcl shell is made with allonge, a, nround the opening b, and' also with an oiisct, c, upon one eide-L tii ,rear port, which lits upon the picker-stad A. E is o metal spring, bent as shown in the' drawings, so that vi l vthe buck or-resd bund d, of the sh'ell C, its nt'etho-curvesythe ends ff bear against thchsck of the picker-etoA, und thus the spring E is vmade to keepthe shell C drsjwn back.. and its flange a, acting upon lthe partDA, keeps that constantly pressed against Athe front of the picker-stnff-A, so that both the sh'ell C und its lling D sro retained in afsecure -and proper position upon the 4steil A. In lieu of themetul spring E, the rec:- -lmnd ci of kthe shell C' may he madev of such shap'ethit a. ruhber-epring con be usedtdkep the shell C und filling Dsecurely in place, ua heiore described'. The p'urt marked F'represents the Ahottomgot theshutticJbox, or one enel of thelay oflthe loom, und ast'here is nothing newclaimed in this part of thof loom, it is not necessary to descrihe it further. The-part marked G is simply n. standard for supporting 'thefpa'rt F, to show the relative positions of the latter und the picker-sta` A. The picircrLetoii' Aia fastened at the 'botton to a rocker, H, of peculiar construction. Rocker H is cored out to receive the lower-end ofpickerstaf ,'ss shown in the drawings, while the rear part y is slottcdout to receive the -lever I, whichhes a curvedrcocssfto receive the round projection m. upouthe rocker H, Iiever I extends. forward and 'hasn front curved recess to t'the round projection n 'upon the slotted rocker-stond er tableJ, whichis to he attached to thi ibottoni of the lay in the usual manner.' A cpi-ing, o, is attached at one end to s projection, p, on the bottomk of lever I, and at the other to the bottom of the lay of the loom, or a strep they connect the-spring en cne end to the leveron the other end of the loom, 'and thus o hviste'the use of two springs. i Thepickerlsta' they be operated or thrown faryrord in any of the well-known modes. d f I The operation is as follows: When the picker-etsii is thrown forward to propelthe shuttle, the extreme forward position which the picker-staii, its rocker, and lever I, occupy, is shown in -blue lines Ain the drawings, while the extreme opposite positions occupied hy thc same pcrtssvhen the shuttle is returned tc the shuttle-box are shown in red linens. When the picker-staii` is druvm forwu'rdthe tongue 1 of Vthe rocker H tits into the slot 2 in table J,'and thereby retains the rocker und picker-stati' from intel-cl displacement, while lever I, by its peculiar construction and cotuhinstion with the recr of rocker H, prevents the letter from sliding forward outof itlproper position, and'spring o prevents it freni slipping beck. The p lsrt mcrked 3 oi' rocker H, and the part 4 of lever I, are both .so fitted to each4 other es to work xithout-binding, and slscn'thout rattling. Itis important tograduolly arrestthc bock motion'oi the shuttle 'before the picker-statici' the locinntrikes sgsinst the 1 back. of theshnttle-box, unduucnydevices'hure heenA contrived to' srrest the force and motion of the picker-steli` i and shuttle after the latter has .properly entered vthe b ox. All such devices have, however, been uttcnded,'1rhen put tc prcoticsl tests ,`wth meny objections.' 13g/my peculinr ccm'bim'xtiou` und srrsrigehnent of the'rccker H with lever'I, tn .hle J, und spring o, the picker-steil' und shuttle src gradually errescdfhy spring o'sfter thests' lhus parsed thepoeition-chown in dark iinesg. 2. Although itmsymove heck to the position shown'in red lines before .it is stopped, spring o will bringit back to the pcsitionzslionn in dork linee#4 'It willhc observed, when rocker Il. ipov'es liack past the position shown in dork' lines, that it elevates thc rear cud of lever I, snd in doi-ng which it hss to Iovemm'tne the resistnnce ot' spring c, whic'h then 'becomes o picicemt'sil. undlshuttlsrrester. I am 'thus enabled to'grsdually arrest they motion of the, shuttle, therebypreventinghe diplacement oi' the yarn npon the cop or bobbin inthe shuttle, wliioliis so liable to ocour when the shuttle is suddenly arrested. In many casos the shuttles are made so that their points stand a. little'in front of the centre of the -slot in which the picker-stati' works, and hy making an offset, 0,' in the hand d of shell C, thc point of the shuttle lwill strike upon the part D in --the centre of the hole fb, andvwhich `point moves in a line nearly parallel tothe bottom of the shuttle'box as the picker-sta# works back and-forth, Spring E may be fastened to the stall by a screw` 5. ns indicated in the drawings. y

Having described my improvements in looms, what I claim ns new, and of my invention, and desire to secure by Letters Patenwis- The combination of the metal shell C, filling D, and springE, or its equivalent, with the top of the picker# staff A, substantially as and for the purposes set forth.
